Problems solved by technology

As a result, an error (a recording and / or reading error) may occur when data is recorded to and / or played back from the optical disc 1.
In addition, if the dirt and dust sucked into the disc drive body 6 adhere to and deposit on other parts, such as the guide shaft 46 and the gear train 49 of the stand moving mechanism 47, etc., the movement of the stand will be adversely affected. impact, and are more prone to problems such as causing trouble finding and tracking

Abstract

SUMMARY OF THE INVENTION The present invention aims to provide a disk drive device which can reduce the thickness of the entire device and which can smoothly clamp and release a disc-shaped recording device to and from a disk table. The disc driving device of the present invention mainly includes: a disc chuck made of non-magnetic parts, which is supported by a chuck supporting member located above the disk-shaped recording medium, and is held by the magnetic attraction force of the disc worktable. Attracting, supported on the chuck support in a floating state; a magnet embedded in the central portion above the disc chuck and magnetized in the vertical direction, and an upper magnetic member, which is arranged above the disc chuck, When the disc tray is in the ejected state, it is used to attract the disc chuck to reach above the clamped position of the disc-shaped recording medium under the magnetic attraction of the magnet; when the disc-shaped recording medium is in the clamped position, The disk working table is close to the magnet, so that the disk chuck is attracted to the disk working table under the magnetic attraction force of the magnet.

Description

[0001] This application is a divisional application of the Chinese patent application with the application number 98109790.1, the filing date being June 8, 1998, and the title "disk drive device". technical field [0002] The present invention relates to the technical field of disc drive devices, preferably a disc drive device for an optical disc drive device, wherein a disc tray is used to load and eject a disc-shaped recording medium (such as an optical disc, etc.). Background technique [0003] A disc drive of the above type has been proposed in an earlier application filed by the assignee of the present application, and reference will be made below to the attached Figures 1 to 14 Explain it. Such as figure 1 As shown, a recess 3 is formed on the upper surface of the tray body 2A of the disc tray 2, and an optical disc 1 as a disc-shaped recording medium is horizontally placed in a recess 3. As shown in FIG. Then, when the tray front panel 2B of the disc tray 2 is push...
